I stand corrected. I agree with you.
But - - ATA/ATAPI-7 is still incorrect and should be corrected
in what it reports as the meaning of 69h/96h and 3Ch/C3h.
Thank You !!!

I don't get that from those documents. That approach would make the
IDENTIFY DEVICE vs. IDENTIFY PACKET DEVICE command selection
indeterminate.
PM 1.1: Port multipliers use 69h/96h.
SATA II 1.2: SEMB (currently attached) use 3Ch/C3h.
SATA II 1.2: SEMB (currently not attached) use FFh/FFh.
ATA/ATAPI-7: ATA devices 00h/00h
ATA/ATAPI-7: ATAPI devices use 1Bh/EBh
SATA devices use 00h/00h, the same as parallel ATA.
SATAPI should use 1Bh/EBh, the same as parallel ATAPI.
